Tropical Storm Irene moved north through central and western New England bringing wind and very heavy rain to New Hampshire. This resulted in flash flooding on small rivers and streams in the mountains and flooding of small rivers and streams as well as main stem rivers farther south. Damage to roads, bridges and culverts was estimated in the millions of dollars in many locations.
